Plotly Example

This markdown document shows plots the hospitals in the california area.

This code first downloads the data and subsets it to make it ready to plot

library(plotly)
#Dowlonad the dataset
hospitalData <- read.csv("https://chhs.data.ca.gov/api/views/ir29-xyw6/rows.csv?accessType=DOWNLOAD")

#Create the data frame
hospitalMapData <- data.frame(name=hospitalData$FACNAME, lat=hospitalData$LATITUDE, lng=hospitalData$LONGITUDE)

Map of California hospitals

This code first sets the map options. Then it plots the hospital locations in California.

map_options <- list(
  scope = 'usa',
  projection = list(type='albers usa'),
  lonaxis = list(range = range(hospitalMapData$lng, na.rm=TRUE)),
  lataxis = list(range = range(hospitalMapData$lat, na.rm=TRUE))
)  

plot_geo(hospitalMapData, lat=~lat, lon=~lng) %>% 
  add_markers(text=~name, hoverinfo="text", ) %>% 
  layout(title="Hospitals in California", geo=map_options)
